Residents in Uttarakhand’s Chamoli district experienced tremors on Sunday as a moderate earthquake, registering a magnitude of 3.7, struck the region. The seismic event occurred at a shallow depth of just 5 kilometers. The National Centre for Seismology confirmed the earthquake’s parameters, noting its occurrence at approximately 10:27 AM IST. The epicenter was located within the Chamoli district, a seismically active zone in the Himalayan foothills, prompting concerns about geological stability in the area.

5.0 Magnitude Earthquake Jolts Pakistan

News Analysis India — Sat, 11 Oct 2025 00:00:00 +0000

A significant seismic event occurred in Pakistan on Saturday, with an earthquake measuring 5.0 on the Richter scale. The tremor was detected by the National Centre for Seismology (NCS). This earthquake originated at a shallow depth of just 10 kilometers, increasing the potential for subsequent aftershocks. The NCS reported the event’s coordinates as Latitude 31.19 N and Longitude 71.04 E. Shallow earthquakes are often more destructive due to the direct impact of seismic waves reaching the surface with less attenuation. Pakistan’s geographical location places it in a highly seismically active zone, situated on the boundary of major tectonic plates. This geological vulnerability means the country frequently experiences seismic activity, with provinces like Balochistan, Khyber Pakhtunkhwa, and Gilgit-Baltistan being particularly susceptible due to their proximity to the collision zones of the Eurasian and Indian plates. Recent seismic activity includes a 4.6 magnitude earthquake that struck the region on October 5.

A 6.3 magnitude earthquake shook the Bay of Bengal early Tuesday, according to the National Centre for Seismology (NCS). The quake, which occurred at a shallow depth of 10 km, was located at 93.37°E longitude and 6.82°N latitude. Authorities are assessing potential impacts. Shortly after, a 6.5 magnitude earthquake hit the Nicobar Islands around 12:12 am IST, at a depth of 10 kilometers. Its epicenter was approximately 259 km west-northwest of Sabang, Indonesia. Despite the strength of the quakes, neither triggered a tsunami alert, according to the United States Geological Survey and the Tsunami Warning System. Social media users shared reactions, with some noting the timing of the Nicobar Islands quake and expressing concerns for safety.

A 3.2 magnitude earthquake shook Haryana at 6:00 AM on Tuesday, according to the National Centre for Seismology (NCS). The epicenter of the earthquake was located in Faridabad, at a depth of 5 kilometers. As of now, there have been no immediate reports of any damage or casualties. The NCS confirmed the event in a post on X, detailing the time, location, and magnitude.

4.4 Magnitude Earthquake Rocks Jhajjar, Haryana; Tremors Felt Across Delhi-NCR

News Analysis India — Thu, 10 Jul 2025 00:00:00 +0000

A 4.4 magnitude earthquake struck the Jhajjar district of Haryana early Thursday morning. The National Centre for Seismology (NCS) confirmed the event. Strong tremors were widely felt throughout Delhi, Noida, Gurugram, and Faridabad, along with neighboring regions. The earthquake occurred at 9:04 am at a depth of 10 kilometers, according to the NCS. The NCS reported the details on X. Earlier, on February 17, a 4.0 magnitude earthquake hit Delhi-NCR at a depth of 5 km, causing residents to evacuate their homes. Delhi is designated as Seismic Zone IV by the Delhi Disaster Management Authority, indicating a high risk of moderate to high-intensity earthquakes.
